Plastic Diaphragm Pumps

Our general purpose plastic air operated double diaphragm pumps (AODD pumps) are available in a polypropylene or PVDF housing. Polypropylene is suitable for use with a wide variety of chemical applications. PVDF offers stronger chemical resistance to both acids and bases, while offering a higher temperature and abrasion protection than polypropylene.
